There is a large body of research that shows the positive effects of exercise on our brain. In short, neuroscientists have found 2 main improvements. First, exercise improves alertness, attention, and motivation. Second, it stimulates the storage of new information in your brain.  In short, exercising will make you smarter.

That is good news. The bad news is that it takes real effort. There are no magic pills, super-effective 2 minute workouts, or other shortcuts. If you want to exercise your brain (your brain can actually increase in size), you have to put in the work. Similar to your muscles, your brain needs training to grow.
